Convolutional Codes and Frequency Responses

abstract:
Frequency responses are introduced as objects that are much finer than transfer functions, and their investigation is carried out via convolutional codes. In particular, a canonical one-to-one correspondence is established between frequency responses and equivalence classes of AR-models. These new objects are important because the study of linear dynamical systems can to a great extent be reduced to the study of them.
